Answer:
It kinda helps but not really
Thanks for trying anyway doe!
Explanation:
Answer:
The density is 1,35 g/cm3
Explanation:
We use the formula for calculate the density
δ =m/V =12,2g / 9,0 cm3= 1,35 g/cm3
Answer:
We can use heat = mcΔT to determine the amount of heat, but first we need to determine ΔT. Because the final temperature of the water is 55°C and the initial temperature is 20.0°C, ΔT is as follows:
ΔT = Tfinal − Tinitial = 55.0°C − 20.0°C = 35.0°C
given the specific heat of water as 1 cal/g·°C. Substitute the known values into heat = mcΔT and solve for amount of heat:
= heat=(75.0 g)(1 cal/ g· °C )(35.0°C) =
= 75x1x35=2625 cal
Aluminum would be my best answer
Answer:
Number of moles = 558.46 mol
Explanation:
Density = 804 g/L
Molecular formula = C13H28
Molar mass = 184.37 g/mol
Distance = 3680 km
Rate = 3.48 L of fuel per 100. km
Volume is calculated as follow;
3.48 = 100
x = 3680
x = 3680 * 3.48 / 100
x = 128.064 L
Number of moles = Mass / Molar mass
Mass = Density * Volume
Mass = 804 * 128.064 = 102963.456 g
Number of moles = 102963.456 / 184.37
Number of moles = 558.46 mol
